31327 also build a canonical type reference.
31328 (build_index_type): When we can't hash an index type (e.g.,
31329 because its maximum value is negative), the index type requires
31330 structural equality tests.
31331 (build_array_type): Build the canonical form of an array type.
31332 (build_function_type): Function types require structural equality,
31333 because they contain default arguments, attributes, etc.
